System for safe high temperature flash memory operation in vehicle involves programming memory before high temperature operation so that each record is stored redundantly

摘要

The system (10) has a temperature sensor (18) measuring a characteristic temperature of the flash memory (12) and a control unit (16) connected to the sensor and memory that forms a cumulative thermal load value by integrating temperature values ands checks records for consistency if a thermal load threshold is exceeded and the temperature is below a safe operating threshold. The records are refreshed or corrected as required. Independent claims are also included for the following: a method of safe high temperature operation of a flash memory.
